Steam Deck Beta Fixes the Bug That Broke Non-Steam Games
A handheld that only runs one storefront’s library is a console. A handheld that runs everything is a Steam Deck — and that distinction just got patched. Valve’s newest Steam Deck client beta fixes the bug that caused non-Steam games to refuse to launch, restoring the shortcuts, emulators, and third-party launchers that make up a genuinely huge share of how Deck owners actually use their hardware.
It’s a small changelog line that punches far above its weight. For anyone whose Deck library is stitched together with Heroic for GOG and Epic titles, Lutris for the stragglers, EmuDeck for retro systems, or plain old ‘Add a Non-Steam Game’ shortcuts for early-access builds and itch.io downloads, a broken launch path isn’t an inconvenience — it’s the entire device going dark. Valve hasn’t detailed the root cause in the beta notes, so we can’t say whether this was a shortcut-handling regression, a Proton compatibility-flag issue, or something in how the client spawns the compatibility tool for non-Steam entries. What we do know is that it’s fixed on the beta branch and not yet on stable.
Beta Channel Math: Update Now or Wait for Stable
Valve’s beta branch has been busy. Recent updates have targeted GPU usage reporting and Linux game crashes, and this one closes the non-Steam launch hole — a sign the client team is working down a backlog of Linux-side regressions rather than shipping new features. If you’re already opted into the beta channel and you depend on non-Steam shortcuts, this is a mandatory update: grab it, relaunch a Heroic game and an EmuDeck system, and confirm both come up before you go anywhere.
If you’re on stable, the calculus is different. Beta client builds can introduce their own regressions, and the stable channel is where Valve parks the version most people should actually be running. The fix will filter down through the normal promotion cycle, and unless your non-Steam library is currently unusable — in which case opting into beta is a perfectly reasonable short-term move — there’s no reason to trade a known-good client for an unknown one. The broader takeaway stands regardless: non-Steam games are a core Steam Deck feature, not a workaround, and Valve treating launch regressions as must-fix beta patches is exactly the behavior that keeps the platform worth recommending to people who own their libraries somewhere other than Steam.
